The default association with the term "database" is relational engines, but non-relational engines are also used quite widely. In this episode Oren Eini, CEO and creator of RavenDB, explores the nuances of relational vs. non-relational engines, and the strategies for designing a non-relationaldatabase.
Relationaldatabases scale up well, but can be painful to scale out when a company has more data than a single database server can manage. On the other hand, non-relationaldatabases (commonly referred to as NoSQL databases) are flexible databases for big data and real-time web applications.
A solid understanding of relationaldatabases and SQL language is a must-have skill, as an ability to manipulate large amounts of data effectively. A good Data Engineer will also have experience working with NoSQL solutions such as MongoDB or Cassandra, while knowledge of Hadoop or Spark would be beneficial.

Two types of databases are used in the development process – RelationalDatabases: MySQL PostgreSQL Microsoft SQL Server Oracle DatabaseNon-RelationalDatabases: MongoDB Cassandra 12.
It is an acronym that stands for MongoDB, Express.js, Angular, and Node.js "MERN" is a term that refers to a combination of technologies used in this stack, which includes MongoDB, Express.js, React.js, and Node.js. . "MERN" MongoDB is used to store the data for the application. using the MongoDB driver.
For example, you can learn about how JSONs are integral to non-relationaldatabases – especially data schemas, and how to write queries using JSON. MongoDB Configuration and Setup Watch an example of deploying MongoDB to understand its benefits as a database system.
Therefore, having a solid grasp of the database is essential. The backend developer must make a relational mapping for the data to be accessible when needed. Therefore, developers employ MySQL, SQL, PostgreSQL, MongoDB, etc., Some of them are PostgreSQL, MySQL, MongoDB, etc. to manage DBMS.
